I don't like to think this, since I just accompanied someone virtually on weds and I do not want to think that in that 25-40 minute window that they were at all filled with regret. They finally got to where they wanted and needed to be and they're free now, from pain, from tears, from everything.
I can't speak for people who are fully impulsive (different than half impulsive, you can have everything planned to a T and a certain situation puts someone over the edge and they start their plan maybe sooner than they thought they would)
